Embodiment Construction
[0017] like figure 1 As shown, the transmission system with a continuously variable transmission device is composed of an input rotor 1, a first gear 2, a second gear 3, a driving pulley 4, a transmission belt 5, a driven pulley 6, and a generator 7.
[0018] The first gear 2 is installed on the input rotor 1, and the rotation of the input rotor is transmitted to the shaft parallel to the input rotor through the second gear 2; the driving pulley 4 is installed on the rotating shaft where the second gear 3 is located, and the driving pulley 4 According to the size of the installation space, choose a fixed-diameter transmission wheel or a variable-diameter transmission wheel. When the driving pulley 4 is a variable-diameter transmission wheel, it needs to be equipped with a diameter adjustment device; when the driving pulley is a fixed-diameter transmission wheel, the transmission belt It needs to be elastic to meet the change of wheel spacing. The driven pulley is a variable d...

The invention belongs to the field of aero-engine accessory structure design, and discloses a power generation system with a stepless speed change device. The power generation system comprises an input rotor, a first gear, a second gear, a driving pulley, a transmission belt, a driven pulley and a generator, wherein the input rotor is used for providing rotating kinetic energy, and the driven pulley is a variable-diameter transmission wheel; and the rotor is sleeved with the first gear, the second gear is meshed with the first gear, the driving pulley and the second gear are installed on a same rotating shaft, the driving pulley and the driven pulley are in transmission through the transmission belt, the transmission ratio is adjusted according to the diameter ratio of the driving pulley to the driven pulley, and the driven pulley drives the generator to generate power. The system is simple in structure, the number of parts is smaller than that of traditional gear transmission, and thetransmission system is small in size and light in weight; and energy loss in transmission is reduced, the generator works in the optimal working speed range through rotor acceleration, the power generation efficiency is high, and the complexity of the transmission system is reduced.
Description
technical field [0001] The invention relates to an aero-engine transmission and power generation system, in particular to a power generation system with a stepless speed change device. Background technique [0002] The traditional transmission system of an aero-engine is a gear transmission. The rotation of the engine rotor drives the gear transmission of the central transmission device, drives the engine accessory transmission device, and then drives the pump accessories on the engine accessory case to work. The traditional gear transmission system needs to transmit the kinetic energy of the rotor to the accessories through a series of gear shifting and transmission, and the required gear system is complex and heavy. [0003] Multi-electric and all-electric engines are one of the development directions of aero-engines in the future. Multi-electric and all-electric engines use more advanced electronic control to replace traditional mechanical hydraulic control, and electroni...
